At least client know you are reliable - one call your be there quick enough. Your job is to solve your client's problem, the earlier you stronger your relationship with your client are.

Also many clients thought you are loser if you do not own a ride. If you cannot even afford a car, you are not doing your business right, if you are not doing your business right, please don't influence me

I don't think I have a different with or without a car. Most of the time I go to their office and they don't even know if I drive. I take Uber and Grab usually. Quite convenient and there is not much different in timing

I heard from someone never drive a car louder than your client, but later I found out that if you drive an impressive car, you will have more friends than you could imagine. Rich people like richer peopler and don't mind giving business to them just to make friend with them
